VAPORIZER FOR INTERNAL-COMBUSTION ENGINES.

To all whom it may concern.-

Be it known that l, .l(NLT flESSELMAN, a citizen of the Kingdom of Sweden, residing at Stockholm, Sweden, ha ve invented new and useful Improvements in Vaporizers for Internal-(loinhustion Engines,

of which the following is a specification.

This invention relates to JoivAs ELIAS iniprm'ements in vaporizers for internal combustion engines where the liquid fuel is introduced into the combustion chamber or chambers of the engins h 1 means of a gaseous agent under pressure, fhr instance compressed air, and more especially to such vaiorizers which have a fuel supply channel communicating by iorts with an oil ehainher which is arranged helow the said fuel supply channel and from which the fuel is forced into the engine by means of the said gaseous agent under pressure.

In order to make my invention fully un derstood it is necessary to give a short declass of vaporizers. and for this purpose I have shown in the acconr panying, drawing both the old and the new construction of the vaporizer.

Figure 1 shows the old construction in longitudinel section and Fig. 2 shows a similar view of myimproved vaporizer.

Referring to Fig. 1, the vaporizer consists of e substantially cylindrical body 1 having its lo wer end ing inserted in a corrcspornling opening in. the head of the working cylinder of the enuine The fuel or oil is supplied into the vaporizer through the channel 2 coniniunieating with an annular groove or fuel supply channel 3 which hv menus of ports 4 (shown by the dotted lines) is in connection with an oil-chamber 5 commonicating hy ports (5 with channels 8 rrxtiriiding to an annular groove 9. Through the hody l is inserted a valve-body 10 around which is a pas we of annular crosssection for the compressed nir (or gas). The uppermost portion 11 of said channel is comparatively nieates by means of channels IL? with the oil chaniher 5, Below the portion 11 ol lhe said passage is a narrow portion 1!) extend ingg downwards to the illllllllllllllinfl't!

annular groove or su ply channel 8 and therefrom into the oil-chan1ber 5 through the ports 4, the latter being very fine in order to prevent the oil from flowing down by itself Into the oil-chamleer and in order to cause a uniform distrihutionof the oil. hen the valve 10 is opened, the air (or gas) rushes through the passage around the valve and through "the inlet-par. sage 14. k Inasmuch as the said passage is Wider below thegroove 9 than above the latter a reduction of the airpressure will arise below the said groove on account of which a partof the air will flow through the channels 12 into the oil-charnber and force the oil contained therein through the ports 6 and channels 8 into the assage around the valve, whereupon the fuel finely distributed will be carried with the air into the romhustion chamber of the engine. The disadvantages of the vaporizer described above are the following: it is necessary to )rovide above the supplv channel 3 a tight lit in order to prevent the oil from coming into the passage around the valve over the upper end of the body 7. It is, however, verv difficult both to make and maintain such tight lit. lhirther the cl'ianuels 4, as already mentioned, must he very line which in using only ne uehpuinp for a plurality f eylilulers easily causes ununilorruitv of the l inally when the slightly loaded s. when only small quantities of fuel are supplied to the SHINE the fuel after having passed through the Ports 4 adheres to the walls of the oil-chainher :i and does not reach the bott m of the some on account whereof the fuel is not i'tnrried with the air in a reliahle runnner. All the sold disrnlvantages are removed ivy lhc present invention according to which the oil-supplv channel 5 is placed below the Oil chanihor instead of above the same as heretofore.

A vaporizer constructed in accordance with my present invention is shown in Fig. 2. The figures l, 3, 5, is. 9, ll), ll, l2. l3 and H irnlir'nlethr some details as in Fig. 1. The iill-s rpplywhennel .l, which is placed helov the oil-rlmmlwr 5. ommunicatcs with tho letter h means of porls 15 which may he compare!ivolv wide, innsnn rh as the fuel lion's upwards in the some hon driven by 'lhc ports l5 therefore cannot of the fu l in a pl rality of cylinders. The light fit ahove the oil-chamber otherwise necessary engine is can be dis )cnsed with. fuel is sup )l ifill into the oil-chmuber from be low, it \Vllfi always keep itself at the bottom of said chamber and consequently he carried with the air in ii rcli. ble manner. The working of the new VH1) irizer is substantially the same as that of the vaporizer shown in Fig. When the valve 10 is opened a part ofthe air rushes through the oil-chamber 5, the ports 15 and the channels 8 carrying with it the fuel contained in the oil-chan1berv A further mlvantage of the vaporizer shown. in Fig. 2 compared with that shown in Fig. I is that the costs of manufacturing and main. aining the same are much reduced on account of its simplified construction.

I la ing now described my invention, what I claini as new and desire to secure by Letters Patent is:

Inasmuch as the A vaporizer of the typc described for interlull combustion engines, comprising it body 1 having a passage for iluid under pressure and also having an oil chamber 5 and an oil-sup- )ly channel 3 conmiunicating w ith said chainiwr and ileccd below the same, it cylinder iortion having an opening receiving said hod y and also having an inlet channel 14 and it fuel supply channel 2, the latter in comniunication with the said channel-3, and e valve-body 10 disposed in the passage of the body 1.

In testimony that I claim the foregoing as my invention, 1 have signed 'my name in presence of two subscribing witnesses.
